Traditional Preparation of Watermelon Frost
Watermelon frost has been used for centuries in Traditional Chinese Medicine (TCM) to treat ailments like sore throats and mouth ulcers. The traditional method of making this remedy involves a fascinating crystallization process. A ripe watermelon is cut open, and its interior is scooped out. Glauber's salt (mirabilite or sodium sulfate) is then added into the hollowed-out rind. The watermelon is sealed, placed into a large unglazed clay vat, and stored in a cool, well-ventilated area.
Over several months, the Glauber's salt interacts with the watermelon's moisture, causing white, crystalline powder—the watermelon frost—to form on the outside of the clay vessel. This powder is carefully scraped off and collected. Some variations of the traditional method involve stuffing the hollowed-out watermelon with other Chinese medicinal herbs, sealing it with its own lid, and hanging it to ferment before scraping off the resulting frost.
Modern Formulations and Herbal Additives
While the traditional method relies heavily on Glauber's salt and watermelon, modern, commercial versions of watermelon frost often include a blend of additional herbs to enhance its therapeutic effects. These additives are carefully selected to complement the cooling and anti-inflammatory properties of the core ingredients.
Common herbal additions in commercial watermelon frost:
- Fritillaria Bulb (Fritillaria cirrhosa): This herb is known in TCM for moistening the lungs and resolving phlegm, making it beneficial for sore throats.
- Licorice Root (Glycyrrhiza glabra): Used to harmonize other herbs and for its soothing properties.
- Menthol: Added for its refreshing, cooling sensation, which provides immediate relief from throat irritation.
- Phellodendron Bark (Phellodendron amurense): This ingredient is often used to clear heat and detoxify.
- Chinese Goldthread Root (Coptis chinensis): Valued in TCM for clearing heat and draining dampness.
- Indigo Puverata Levis (Qing Dai): Included for its anti-inflammatory and antiseptic qualities.

The Function of Watermelon Frost in TCM
Within Traditional Chinese Medicine, watermelon frost is considered a 'cold' or 'cooling' remedy. This means it is used to address conditions caused by excess 'heat' in the body, which can manifest as inflammation, pain, and redness. The herbs within the compound work synergistically to clear this excess heat and soothe the affected area. The combination of watermelon extract, which has a cooling effect, and other herbs with specific functions makes it a powerful topical remedy for oral and throat inflammation.
Modern research has even explored the anti-inflammatory and antibacterial properties of watermelon frost. A 2022 study, for example, found that watermelon frost combinations were effective against oral ulcers. Another study compared watermelon frost to ribavirin aerosol for treating oral herpes in children with hand, foot, and mouth disease and found watermelon frost to be more effective. These studies indicate that watermelon frost's traditional uses have some basis in its active properties.
Conclusion
In conclusion, what is watermelon frost made of is a complex answer that spans both traditional, simple methods and modern, sophisticated formulations. Traditionally, it is a crystalline powder created from watermelon and Glauber's salt fermented in a clay vat. Today's commercial products build on this foundation, adding a carefully balanced blend of Traditional Chinese Medicine herbs such as fritillaria bulb, licorice root, menthol, and phellodendron bark to enhance its therapeutic effects. The resulting compound offers a natural, herbal remedy for sore throats, mouth ulcers, and other oral inflammations, grounded in centuries of TCM practice and increasingly supported by modern research. While its core ingredients remain derived from the watermelon, the full formula is a sophisticated herbal preparation. Learn more about the traditional preparation and its history in Chinese culture.
The Evolution of Xigua Shuang
For generations, the production of Xigua Shuang (watermelon frost) was a time-intensive process demanding patience and specific conditions. The slow fermentation and crystallization required months in a cool, well-ventilated space. Modern methods, however, have evolved to meet commercial demand, using more efficient processes like fermentation with specific high-salt-resistant strains or freeze-drying techniques. These techniques speed up production without compromising the core medicinal properties. Regardless of the preparation method, the essence of watermelon frost as a cooling and detoxifying remedy remains unchanged in TCM. From ancient tradition to modern production, the core purpose is consistent: to bring relief to those suffering from oral and throat irritation. The use of various additional herbs also showcases a rich history of refinement within TCM to optimize the formula's effects, with specific combinations being developed over time to address particular symptoms or conditions. This reflects a commitment to both tradition and innovation within herbal medicine. The practice of using complex herbal formulas like watermelon frost highlights a holistic approach to health, where multiple ingredients work together to treat a condition from multiple angles, rather than isolating a single active compound.
